Drones to search for missing MH370

Ocean Infinity, a Texas-based firm that specializes in seabed exploration technology, told CNNMoney on Friday that it has submitted an offer to search for the remains of the Boeing 777 that disappeared more than three years ago with 239 people on board.

The company declined to reveal the exact terms of the proposal, but said it's willing to "take on the economic risk of a renewed search."

It's a bold move to offer to shoulder the financial burden of trying to help solve one of modern aviation's greatest mysteries. The original underwater search dragged on for years and cost roughly $150 million.
